Nasty weather set in Eastern Europe

Uncharacteristic weather has set in the east of Europe. Nasty weather hit Poland and substantially damaged the future crops. Because of complicated weather conditions (snowfall, poor visibility), Moscow airports switched to the winter service mode. The plains and runways are strewed with deicing agents. Weather forecast says, the next day in Belarus will be not as it should be in May, either. Ground frosts at night and -3 degrees Celsius. In the daytime, rain and sleet are expected, but the air will be 5 to 10 degrees warm.
